What it means What to do
amberGENERAL FAILURE INDICATION
(Versions with multifunction display)
The warning light turns on in the following
circumstances:
If the fuel inertia cut-off switch is activated
Light failure (rear fog lamps, direction indicators,
brake lights, number plate lights, side lights, daytime
running lights, main beam automatism, trailer direction
indicators, trailer side lights)The failure relating to these lights could be: one or
more blown bulbs, a blown protection fuse or a break
in the electrical connection.
Airbag warning light failure (generic failure warning
light flashing)In this case, the warning light may not indicate
problems with the restraint systems. Before
continuing, contact a Fiat Dealership to have the
system checked immediately.
Rain sensor failure
Diesel filter sensor failure
Trailer connection failure
Audio system failure
Engine oil pressure sensor failure
Parking sensor failure
Water in diesel fuel filterContact a Fiat Dealership as soon as possible to have
the fault fixed.

108)Airbags may be deployed if another
vehicle crashes into yours if the key is
inserted and on, even if the engine is not
running and your vehicle is standing.
Therefore, even if the car is stationary,
when an active front passenger airbag is
fitted, DO NOT install rear facing child
restraint systems on the front passenger
seat. Deployment of the airbag following an
impact could cause fatal injuries to the
child. Therefore, always deactivate the
passenger side airbag when a rearward
facing child restraint system is installed on
the front passenger seat. The front
passenger seat must also be positioned
back as far as possible in order to prevent
the child restraint system from coming
into contact with the dashboard.
Immediately reactivate the passenger
airbag as soon as the child restraint system
has been removed. Also remember that, if
the key is turned to STOP, none of the
safety devices (airbags or pretensioners)
will be deployed in the event of collision.
Non-deployment in such cases does
not indicate a system malfunction.
109)Have the airbag system checked by a
Fiat Dealership if the car was stolen, if
theft was attempted, or if the car was
subjected to vandalism or flooding.
110)By turning the ignition key to MAR
position, the LED on the
button located
on the dashboard lights up (the time it
stays lit up can vary depending on the
market), to check that the button LED is
working correctly.
111)Do not wash the seats with water or
pressurised steam (wash by hand or at
automatic seat washing stations).112)The front airbag is designed to be
deployed for impacts of a greater intensity
than for the pretensioners. For impacts
whose intensity falls between the two
levels, normally, only the pretensioners will
be activated.
113)Do not affix rigid objects to the
garment hooks or support handles.
114)The airbag does not replace seat
belts but increases their efficiency.
Furthermore, since front airbags are not
deployed in low-speed frontal impacts,
side impacts, rear shunts or roll-overs, the
passengers are protected only by the
seat belts which must therefore be
fastened at all times.
115)In some versions, in the event of a
LED
OFFfailure (located on the
dashboard trim), thewarning light on
the instrument panel turns on and the
passenger side bags are deactivated. In
some versions, in the event of a LED
ONfailure (located on the dashboard
trim), thelight on the console turns on.

When necessary, you can engage
1st ,RorNwith the engine off, the key
in the MAR-ON position and the brake
pressed. In this case, gear shifts must
be made allowing at least 5 minutes
to elapse between one gear shift and
the next to safeguard the operation
of the hydraulic system and the pump
in particular;
for hill starts, accelerating gradually
but fully straight after having released
the handbrake or the brake pedal
allows the engine to greatly increase the
number of revs and tackle steeper
slopes with more torque at the wheels.
on gradients > 5% it is prohibited
to engage the 2ndgear with vehicle
stationary.
HANDBRAKE
Handbrake engagement:The
handbrake lever is located to the left of
the driver's seat. Pull the lever upwards
to engage the handbrake and ensure
that the vehicle does not move.
Handbrake disengagement:slightly
raise the lever, hold the button A
pressed and check that the
warning light switches off on the
instrument panel.
Press the brake pedal when carrying
out this operation to prevent the vehicle
from moving accidentally.IMPORTANT Make sure that the
handbrake is engaged in such a way as
to ensure the stationing of the vehicle,
especially in the case of steep slopes
and full load.
IMPORTANT Apply the handbrake only
when the vehicle is at a standstill or
with the vehicle in motion only in the
event of a failure in the hydraulic
system. If exceptional use is made of
the handbrake with the vehicle in
motion, moderate traction is advisable
in order not to cause locking of the
rear end with consequent swerving of
the vehicle.
WARNING
117)Never leave children unattended in
the vehicle. Always remove the ignition key
when leaving the vehicle and take it out
with you.
WARNING
22)If the vehicle is equipped with
self-levelling air suspension, always check
that there is sufficient space above the roof
and around the vehicle when parking.
Indeed, the vehicle could raise (or lower)
automatically depending on load or
temperature changes.
MANUAL
TRANSMISSION
To engage the gears, press the clutch
pedal fully and put the shift lever into
the required position (the diagram
is shown on the knob A fig. 126).
To engage 6th gear (where provided),
operate the lever by pressing it towards
the right in order to avoid engaging
4th gear by mistake. The action is
similar for shifting from 6th gear to 5th
gear.
IMPORTANT Reverse may only be
engaged when the vehicle is at a
standstill. With the engine running, wait
for at least 2 seconds with the clutch
pedal fully pressed before engaging
reverse to prevent damage to the gears
and grating.

STARTING AND DRIVING

ADDITIVE FOR
DIESEL EMISSIONS
ADBLUE (UREA)
System description
The vehicle is equipped with an UREA
fuel injection system and a Selective
Catalytic Reduction catalyst to meet the
emission standards.
These two systems ensure compliance
with the diesel emissions requirements;
at the same it maintains fuel saving
levels, driveability, torque and power.
For the system messages and warnings
refer to the "Warning lights and
messages" paragraph in the "Knowing
the instrument panel" section.
Notes
When you stop the vehicle you
could hear a distinct click coming from
under the vehicle due to the UREA
injection system, this is normal.
The UREA injection system pump
continues to operate for a short period
of time after the engine is switched
off, to purge the circuit. This is normal,
and you can still hear its noise from
under the vehicle.
VERSION WITH
METHANE SYSTEM
(Natural Power)
38) 39)
INTRODUCTION
The "Natural Power" version of the Fiat
Ducato features two fuel system, one
primary natural gas (methane) system
and one emergency petrol system.
METHANE CYLINDERS
The vehicle is equipped with five
cylinders (total capacity of about 218
litres) located under the vehicle floor
and protected by two special shields.
The cylinders are the tank that contains
the methane in its compressed
gaseous state (nominal pressure of 200
bar at 15°C). The methane, stored in
the cylinders at high pressure, flows
through a dedicated pipe to reach the
pressure regulator/reduction unit which
supplies the 4 methane injectors at
low pressure (about 6 bar).
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years
from the vehicle registration date or
in accordance with specific
regulations in individual countries.IMPORTANT If gas is smelled, switch
from methane operation to petrol
operation and immediately go to a Fiat
Dealership to have the vehicle checked
and possible system faults excluded.
FUEL SWITCHING
LOGICS
Management of switching between the
two different fuel supplies is fully
automatic, and carried out by the
engine control unit.
When the residual amount of methane
drops below 1/5 of the cylinder
capacity, the lowest level and the edges
of the other levels flash to indicate the
reserve state and that refuelling fig. 140
is required.
If the methane runs out, it is
automatically switched to petrol; on the
display, all the empty segments stop
flashing and then the
indicator near
the CNG icon fig. 141 turns on.
Having reached the reserve methane
pressure threshold, and completely
filled the methane tank, the system
forces the switch to petrol for 5
seconds, with the aim of keeping the
petrol fuel supply system fully efficient.

STARTING AND DRIVING

TOWING TRAILERS
IMPORTANT NOTES
The vehicle must be provided with a
type-approved tow hook and adequate
electrical system to tow caravans or
trailers. Installation should be carried
out by specialised personnel who
will issue the required papers for
travelling on roads.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that when towing a trailer,
steep hills are harder to climb, the
braking spaces increase and overtaking
takes longer depending on the overall
weight.
Engage a low gear when driving
downhill, rather than constantly using
the brake.
The weight of the trailer on the vehicle
tow hook will reduce the loading
capacity of the vehicle by the same
amount. Consider the weight of the
trailer fully laden, including accessories
and luggage, to make sure you do
not exceed the maximum towable
weight (shown on the vehicle
registration document).Do not exceed the speed limits specific
to each country you are driving in, in
the case of vehicles towing trailers.
In any case, the top speed must not
exceed 100 km/h.
You are advised to fit a suitable
stabiliser to the trailer drawbar.
In the vehicles equipped with parking
sensors, after fitting the tow hook
malfunctioning warnings may be
displayed, as some parts (tow bar, ball
tow hook) may be within the sensor
detection range. In this case the
detection range must be adjusted or
the parking assistance function must be
deactivated.
In vehicles equipped with "Comfort-
matic" transmission, make sure that the
gearbox is in neutral (N) (checking that
the vehicle moves when pushed) and
proceed in the same way as for towing
a normal vehicle with manual
transmission. If the gearbox cannot be
put in neutral, do not tow the vehicle
and contact a Fiat Dealership.
137) 138)
INSTALLING THE TOW
HOOK
The towing device should be fastened
to the body by specialised technicians
according to any additional and/or
integrative information supplied by the
Manufacturer of the device.
The towing device must meet current
regulations with reference to Directive
94/20/EC and subsequent
amendments.
For any version the towing device used
must match the towable weight of the
vehicle on which it is to be installed.
For the electric connection a standard
connector should be used which is
generally placed on a special bracket
normally fastened to the towing device,
and a special ECU for external trailer
light control must be installed on the
vehicle. For the electrical connection, 7
or 13 pin 12 V DC connections are to
be used (CUNA/UNI and ISO/DIN
Standards). Follow the instructions
provided by the vehicle manufacturer
and/or the tow hitch manufacturer.
Any electric brake (or electric winch,
etc.) should be supplied directly by the
battery through a cable with a section
of at least 2.5 mm
2.
IMPORTANT Electric brakes or other
devices must be used with engine
running.

parts using special compounds
available commercially;
sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glass;
slightly open the windows;
cover the vehicle with a piece of
fabric or perforated plastic sheet. Do
not use compact plastic tarpaulins,
which prevent humidity from
evaporating from the surface of the
vehicle;
inflate tyres to +0.5 bar above the
standard specified pressure and check
it at intervals;
do not drain the engine cooling
system.
IMPORTANT If the vehicle is equipped
with an alarm system, switch off the
vehicle alarm with the remote control.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to

170)If different tyres from the ones
supplied with the vehicle are used, it may
not be possible to carry out the repair. If
the tyres are replaced, it is advisable to use
those approved by the manufacturer.
Consult a Fiat Dealership.
WARNING
49)In the event of a puncture caused by
foreign bodies, the kit may be used to
repair tyres showing damage on the tread
or shoulder up to max 4 mm diameter.
WARNING
3)Replace the bottle if the sealant has
expired. Dispose of the bottle and the
sealant properly. Have them disposed of in
compliance with national and local
regulations.
JUMP STARTING
If the warning lightremains on
continuously on the instrument panel,
contact the Fiat Dealership immediately.
JUMP STARTING
If the battery is flat, it is possible to start
the engine using an auxiliary battery
with the same capacity or a little higher
than the flat one.
It is advisable to contact a Fiat
Dealership to check/replace the battery.
171)
Proceed as follows to start the vehicle:
lift the flap A fig. 199 to access
the positive battery terminal connection;
connect the positive terminals (+
mark near the terminal) of the two
batteries using a suitable cable;
use a second lead to connect the
negative terminal (–) of the auxiliary
battery to the earth point as shown in
fig. 200;
start the engine;
when the engine has been started,
remove the cables reversing the order
above.
If after a few attempts the engine does
not start, do not persist but contact
the nearest Fiat Dealership.
IMPORTANT Do not directly connect
the negative terminals of the two
batteries: sparks could ignite explosive
gas released from the battery. If the
auxiliary battery is installed on another
vehicle, avoid any metal parts on the
latter and the vehicle with the flat
battery from accidentally coming into
contact.

WARNING
172)Battery fluid is poisonous and
corrosive: avoid contact with your skin and
eyes. The battery should be charged in a
well ventilated place, away from naked
flames or possible sources of sparks:
danger of explosion and fire.
173)Do not attempt to charge a frozen
battery: it must be thawed first, otherwise it
may explode. If freezing has occurred, the
battery should be checked by skilled
personnel to make sure that the internal
elements are not damaged and that the
body is not cracked, with the risk of leaking
poisonous and corrosive acid.
FUEL CUT-OFF
SWITCH
The vehicle is fitted with a safety switch
that, in the event of a crash, comes
into operation by cutting off the fuel
supply and turning off the engine as a
consequence.
When the inertia switch cuts in, it cuts
off the fuel supply and also activates
the hazard warning lights, side lights
and courtesy lights while releasing
all the doors and displaying the relevant
message; they are deactivated by
pressing button A. On some versions,
there is also a safety relay that activates
in the event of impact to cut off the
electrical supply. In this way, fuel is
prevented from escaping if the pipes
are broken and the formation of sparks
or electrical discharges following
damage to the vehicle electrical
components is avoided.
